Description

Technical Field

[0001] This utility model relates to the technical field of slurry filtration equipment, specifically to a material removal device for a discharge trough. Background Technology

[0002] A disc vacuum filter is a device that uses vacuum as the filtration power to separate solids and liquids in a slurry. In the filter chamber, the slurry adheres to the filter disc and forms a filter cake in the adsorption zone due to the pressure difference created by the vacuum pump on both sides of the filter medium. Then, the filter cake leaves the liquid surface and continues to lose water under the action of vacuum. The filtrate passes through the filter cloth, through the filtrate pipe, and is discharged from the distribution head. The filter cake is discharged into the discharge trough by the back-blowing air in the discharge zone. The entire operation process is carried out continuously in a cycle.

[0003] In the prior art, when a disc vacuum filter performs solid-liquid separation on a slurry, some of the solid materials produced have a certain degree of viscosity or stickiness. The material's humidity, particle size distribution, and other characteristics also affect its stickiness, which makes it easy for the material to stick on the guide plate of the discharge trough. If it is not cleaned in time, it may gradually accumulate and cause the discharge plate to become blocked. Utility Model Content

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] Example 1:

[0058] like Figures 1 to 5 As shown, this utility model provides a material removal device for a discharge trough, including: a disc vacuum filter 1, the disc vacuum filter 1 including a support frame 101 arranged on the disc vacuum filter 1 for supporting the disc vacuum filter 1, and a guide plate 102 arranged on the disc vacuum filter 1 for discharging materials.

[0059] In order to facilitate the transfer of materials generated by the vacuum filter 1, a material transfer structure for transferring the materials discharged from the disc vacuum filter 1 is arranged on the disc vacuum filter 1.

[0060] The material transfer structure includes a support base 2 arranged on one side of the support frame 101, an arc-shaped material trough 201 arranged on one side of the support base 2 for centralized material collection, a linkage shaft 202 rotatably installed on the inner wall of the arc-shaped material trough 201, a spiral pusher plate 203 fixedly sleeved on the linkage shaft 202, the spiral pusher plate 203 contacting the inner wall of the arc-shaped material trough 201, a drive assembly arranged on the linkage shaft 202 for driving the linkage shaft 202 to rotate, and a transmission sprocket 204 driving the linkage shaft 202 to rotate when rotating, so that the linkage shaft 202 drives the spiral pusher plate 203 to rotate, thereby causing the rotating spiral pusher plate 203 to push out the residue in the arc-shaped material trough 201.

[0061] Specifically, the drive assembly includes a first transmission sprocket 204 fixedly mounted on the linkage shaft 202, a transmission chain 205 mounted on the first transmission sprocket 204, a second transmission sprocket 206 mounted on the transmission chain 205, a reciprocating screw 207 arranged on one side of the second transmission sprocket 206 for driving the second transmission sprocket 206 to rotate, a motor 208 with its output end arranged at one end of the reciprocating screw 207 for driving the reciprocating screw 207 to rotate, and a bearing seat 209 arranged above the support base 2 for supporting the reciprocating screw 207. The bearing seat 209 is rotatably mounted on the reciprocating screw 207. By turning on the motor 208, its output end can drive the reciprocating screw 207 to rotate. The rotating reciprocating screw 207 can drive the second transmission sprocket 206 to rotate, thereby driving the first transmission sprocket 204 to rotate through the transmission engagement with the transmission chain 205.

[0062] Example 2:

[0063] Based on Example 1, in order to prevent material from sticking to the inner wall of the guide plate 102, a scraping structure for scraping the material at the discharge port of the disc vacuum filter 1 is arranged on the material transfer structure.

[0064] The scraping structure includes a scraper plate 3 for scraping off residue from the guide plate 102. The scraper plate 3 is in contact with the surface of the guide plate 102. A connecting rod 301 is slidably installed inside the support frame 101. The connecting rod 301 is arranged on the scraper plate 3. A threaded slide 302 is arranged at one end of the connecting rod 301. The threaded slide 302 is threaded onto the reciprocating screw 207. The threaded slide 302 is slidably installed above the support seat 2. The rotating reciprocating screw 207 can drive the threaded slide 302 to slide back and forth through the threaded engagement with the threaded slide 302. This causes the threaded slide 302 to drive the connecting rod 301 to move back and forth. The connecting rod 301 then drives the scraper plate 3 to scrape back and forth on one side of the guide plate 102.

[0065] Example 3:

[0066] Based on Example 1, in order to facilitate the shaking off of the material on the guide plate 102 and further improve the cleaning effect of the guide plate 102, a knocking structure for shaking off the material at the discharge port of the disc vacuum filter 1 is arranged on the disc vacuum filter 1.

[0067] The striking structure includes a fixed shaft 4 arranged on the support frame 101, a movable wheel 401 rotatably sleeved on the fixed shaft 4, a striking rod 402 arranged on the outer surface of the movable wheel 401, and a linkage component for driving the movable wheel 401 to reciprocate. The striking rod 402 contacts one side of the guide plate 102. When the movable wheel 401 rotates, it can drive the striking rod 402 to flip, so that the striking rod 402 strikes the guide plate 102, forcing the guide plate 102 to vibrate.

[0068] Specifically, the linkage assembly includes a transmission shaft 404 rotatably mounted inside the support frame 101, an intermittent gear 405 fixedly sleeved on the transmission shaft 404, an intermittent toothed ring 406 arranged on the outer surface of the movable wheel 401, the intermittent toothed ring 406 meshing with the intermittent gear 405, a transmission sprocket 407 fixedly sleeved on the transmission shaft 404, the transmission sprocket 407 being driven to drive the transmission shaft 404 to rotate, and the transmission shaft 404 driving the intermittent gear 405 to rotate. When the intermittent gear 405 rotates, it can drive the movable wheel 401 to rotate on the fixed shaft 4 through meshing with the intermittent toothed ring 406.

[0069] The striking structure also includes a torsion spring 403 sleeved on the fixed shaft 4 to drive the rotation of the movable wheel 401 for resetting. One end of the torsion spring 403 is arranged on the inner wall of the movable wheel 401, and the other end of the torsion spring 403 is arranged on the outer surface of the fixed shaft 4. The rotation of the movable wheel 401 will compress the torsion spring 403. When the continuously rotating intermittent gear 405 disengages from the intermittent gear ring 406, the compressed torsion spring 403 will be released and drive the movable wheel 401 to rotate and reset.

[0070] Working principle:

[0071] The residue generated during the operation of the disc vacuum filter 1 falls onto the guide plate 102, and then slides down into the arc-shaped trough 201, causing the residue to fall into the gap of the spiral pusher plate 203. Turning on the motor 208 causes its output end to drive the reciprocating screw 207 to rotate. The rotating reciprocating screw 207 drives the second transmission sprocket 206 to rotate, thereby causing the second transmission sprocket 206 to drive the first transmission sprocket 204 and the third transmission sprocket 40 through the transmission engagement with the transmission chain 205. 7. The rotating transmission sprocket 204 drives the linkage shaft 202 to rotate, which in turn drives the spiral pusher plate 203 to rotate. This causes the rotating spiral pusher plate 203 to push out the residue in the arc-shaped material groove 201. Furthermore, the rotating reciprocating screw 207, through its threaded engagement with the threaded slide 302, drives the threaded slide 302 to slide reciprocally above the support base 2. This causes the threaded slide 302 to drive the connecting rod 301 to move reciprocally, and the connecting rod 301, in turn, drives the scraper plate 3 to move along the guide... The material guide plate 102 is scraped back and forth on one side to prevent residue from adhering to it. Simultaneously, the rotating transmission sprocket 407 drives the transmission shaft 404 to rotate, which in turn drives the intermittent gear 405. When the intermittent gear 405 rotates, it meshes with the intermittent gear ring 406, causing the movable wheel 401 to rotate on the fixed shaft 4. This, in turn, moves the striking rod 402 away from contact with the side of the material guide plate 102. Simultaneously, the rotation of the movable wheel 401 compresses the torsion spring 403. When the intermittent gear 405 disengages from the intermittent gear ring 406, the compressed torsion spring 403 is released and drives the movable wheel 401 to rotate and reset. This causes the movable wheel 401 to drive the striking rod 402 to flip and reset, so that the striking rod 402 strikes the guide plate 102, forcing the guide plate 102 to vibrate. As the intermittent gear 405 rotates repeatedly, the striking rod 402 can reciprocate to strike the guide plate 102, further improving the removal effect of residue on the surface of the guide plate 102.

[0072] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
